图2. 北半球中高纬度地区植被春季物候的温度“滞后”效应统计。时间段数字表示植被春季物候所在月份的前(n-1)个月的时间段, 例如, 1表示春季物候发生的当月, 2表示植被物候发生前1个月, 即当月和物候发生前1个月时间段的月平均温度。
Fig. 2. The “lag effect” of mean temperature on spring green-up onset in mid- to high-latitude regions of Northern Hemisphere. The values for period show the month(s) precede the average start of season. E.g. value 1 represents the month of start of spring, and 2 the preceding month before the start of month, calculated as the average temperature between the month of phenological event and the preceding month.
